Shooting HDR is getting easier, but making it viewable still presents difficulties. However, anyone uploading to YouTube in HDR should find it easier soon, provided they use Atomos recorders.
Atomos has worked with YouTube’s development team to showcase HDR production and make it easier to upload either PQ or HLG in UHD or 4K. Together they have implemented a set of parameters for HDR signals for set-top boxes, gaming consoles and TV sets, and Atomos has defined a header structure compatible with YouTube from its ProRes files so YouTube’s servers will correctly encode it.
They hope this will go forward as a standard.
Users of its seven-inch recorder/monitors or 19-inch Sumo will soon be able to select Log mode, apply a transform and set a destination.
They could choose PQ/BT.2020 or HLG before starting to record, and as soon as they close the file, the QuickTime wrapper will encase all the parameters YouTube expects for HDR.
